Analysis of location uncertainty for a microearthquake cluster: A case study
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
In many reservoirs, an increase in permeability and conductivity is achieved by hydraulic fracturing/stimulations which open cracks and fractures that then act as pathways for fluids to navigate in the subsurface. Mapping, ...
Joint microseismic event location with uncertain velocity
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
We study the problem of the joint location of seismic events using an array of receivers. We show that locating multiple seismic events simultaneously is advantageous compared to the more traditional approaches of locating ...
A unified Bayesian framework for relative microseismic location
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
We study the problem of determining an unknown microseismic event location relative to previously located events using a single monitoring array in a monitoring well. We show that using the available information about the ...
Carbon sequestration monitoring with acoustic double-difference waveform inversion: A case study on SACROC walkaway VSP data
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
Geological carbon sequestration involves large-scale injection of carbon dioxide into underground geologic formations and is considered as a potential approach for mitigating global warming. Changes in reservoir properties ...
